(Ti,Zr,Hf,Ta)CN/SiCN: A new ultrahigh-temperature ceramic nanocomposite with excellent mechanical properties and ablation resistance

Journal of Advanced Ceramics
Dense monolithic (Ti,Zr,Hf,Ta)CN/SiCN ceramic nanocomposites are prepared via the pyrolysis of novel (Ti-,Zr-,Hf-,Ta)-containing single-source precursors (SSPs) and spark plasma sintering (SPS) with a high heating rate.

Ultrahigh-Temperature Ceramics [PDF]

, 2007
Ultrahigh temperature ceramics (UHTCs) are a class of materials that include the diborides of metals such as hafnium and zirconium. The materials are of interest to NASA for their potential utility as sharp leading edges for hypersonic vehicles.

Creep of HfB2-based UHTCs up to 2000oC [PDF]

, 2017
Ultra-high temperature ceramics (UHTCs) are promising candidates for hypersonic applications as a consequence of their high melting points, in excess of 3000 ºC for ZrB2 and HfB2 UHTCs. The UHTCs community has traditionally focused on development of more

Single-source-precursor synthesis and air-plasma ablation behavior of (Ti,Zr,Hf)C/SiC ceramic nanocomposites at 2200 °C

Journal of Advanced Ceramics
Dense monolithic (Ti,Zr,Hf)C/SiC ceramic nanocomposites with four different molar ratios of metallic elements in the (Ti,Zr,Hf)C phase (i.e., Ti : Zr : Hf = 1 : 1 : 1, 2 : 3 : 5, 2 : 3 : 3, and 1 : 2 : 1) were prepared upon pyrolysis of novel (Ti,Zr,Hf ...

Intrinsic Thermal Transport Properties of ZrB2 From Room Temperature to Melting Point

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Zirconium diboride (ZrB2) is a promising material for extreme‐environment applications, yet its intrinsic high‐temperature thermophysical behavior remains uncertain: Experiments are highly sensitive to processing conditions, simulations omit key mechanisms, and both rarely reach ultrahigh temperatures. Here, we predict the thermal conductivity

High-entropy ceramics: From paradigm formation to ordered development

Journal of Advanced Ceramics
High-entropy ceramics (HECs), defined as single-phase inorganic solid solutions comprising five or more principal elements in equimolar or near-equimolar ratios, have emerged as a frontier and hotspot in materials science over the past decade.

Single‐source precursor synthesis of a compositionally complex early transitional metal nitride (V, Nb, Ta, Mo, W)Nx and its high temperature stability

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Compositionally complex transitional metal nitrides are an interesting class of ceramics with superior chemical, thermal, and mechanical stability, with a high potential in ultra‐high temperature applications and catalysis. The exceptionality in the properties may partly be explained as a consequence of their high configuration entropy ...
